I suppose I'd do it in this order 1) Create the domain and all the users on the new server. Given that it's such a small domain, I'd do it by hand you could dump the db but then you'd have to drop the unnecessary tables. I'm not sure of a way to extract one table in mysql. 2) Point the email clients POP or IMAP to the new server. This would be easy if your using a domain name. 3) Route email to the new server. (Mail would not be received between the last two steps). 4) Copy the mail for the domain over. I would not use unison for this. Recently, I used 'scp' with the recurse option for each user in the domain but had to change the permissions on the new files to vpopmail.vchkpw.
